In 2006, Devil's Due Publishing began releasing a 12-issue limited series comic book adaptation of Killer7 that was written and drawn by the staff of independent company Kinetic Underground. The plot of the comic was somewhat streamlined from the plot of the game, but the writers deliberately did not spoonfeed information to readers in an effort to still stay true to the game. However, due to low sales, the comic was cancelled after six issues, four of those being properly numbered Issues #1-4, as well as a promotional Issue #0 that was released as a bonus with copies of Killer7 pre-ordered from EB Games, and a promotional Issue #½ that was only released at San Diego Comic Con 2005.
